How can the rate of a reaction that produces a gas be measured?

By collecting the gas and recording its volume over time

Why does increasing temperature increase the rate most strongly?

More collisions reach the activation energy and collisions are more frequent

A substance that speeds a reaction without being used up

Lowers it by providing an alternative pathway

The forward and backward reactions occur at the same rate in a closed system

A lower temperature gives a higher yield but the reaction would be too slow

One that releases energy and warms the surroundings

Q equals m times c times delta T

What are the raw materials for the Haber process?
What catalyst is used in the Haber process?

What is an exothermic reaction?
On an energy level diagram for an exothermic reaction, where are the products?
Which equation is used in calorimetry to find the energy transferred?
